IMPROVEMENT IN HUB-ATTACHING DEVIC ES.

Specification forming part of Letters Patent N 0. 217,086, dated July 1,1879 application filed May 9, 1879.

To all whom it may concern:

Be it known that I, GoT'rLiEB FINKBEINER, of Philadelphia, Pennsylvania,have invented a new and useful Improvement in Carriage- Axle Boxes, ofwhich the following is a specification.

My invention relates to certain improvements in the carriage-axle boxesfor which Letters Patent of the United States were granted to Louis A.Mayall and myself on the 28th day of January, A. D. 1879, No. 211,767,the objects of my present improvements being to simplify and cheapen theconstruction of the box and increase the efficiency of the same-objectswhich I'attain in the following manner, reference being had to theaccompanyin g drawings, in which- Figure l is a longitudinal sectionalview of an axle-box with my improvements, the axle being shown inelevation; Fig. 2, a view of the rear face of the box with the axle andthe fastening devices removed therefrom, and Fig. 3 a perspective viewof the different parts of the fastening detached from each other.

A is the axle, which has a collar, a, formed thereon, and B is theaxle-box, which is adapted to the central opening of the hub in theusual manner, and is enlarged in diameter at and near the inner end, arecess, b, being formed in this part of the box for the reception of thecollar a on the axle, as shown in Fig. 1. r

The rim of the enlarged portion of the axlebox has on its inner edgesegmental ribs 0?, with intervening spaces 6, three ribs and threespaces beingformed in the present instance, but more or less being usedin practice, if desired.

Fitting snugly, but so as turn freely, 011 the portion f of the axle Ais a sleeve, D, on one end of which is formed a ring, 2', with ribs m.The ringt' ismaintained in its proper longitudinal position within thebox B by means of a cover-plate, a, adapted to the inner face of thebox, this cover-plate being so secured to the box as to be capable ofturning independently of the same, a pin, 8, on the box, adapted to anopening, it, in the cover-plate, being relied upon in the presentinstance to prevent such turning.

The sleeve D is threaded, and to this thread is adapted a nut, F, whichacts as a jam-nut, as described hereinafter, to prevent the backwardmovement of the sleeve.

In fitting the box to the axle and securing it against longitudinaldisplacement, the box is first slipped on the axle until the collar torests in the recess b. The ring i is then fitted to. the opening in theinner end of the box, the ribs on coinciding with the spaces between theribs d of the box. The cover-plate n being applied, the sleeve D isturned so as to cause the ribs m of the ring z to engage with the ribs dof the box, and after the sleeve D has been turned to the proper extentthe jamnut F is screwed up against the face of the plate 11, so as toprevent backward movement of the sleeve. The box and sleeve now form, ineffect, one structure, which can turn freely on the axle, but whichcannot move longitudinally on the same, oiving to the collar a.

To prevent rattling, a washer, w, of leather, cork, or other elasticmaterial, is introduced between one face of the collar a and theshoulder formed by the enlargement of the box B, and a similar washerbetween the other face of said collar and the ring i,- and in order tocompensate for the effects of wear on these washers and on the ribs m,so as to keep the box constantly tight, the'said ribs in are madetapering, as shown in the perspective view, Fig. 3.

Undue-movement of the sleeve D and its ring i may be prevented by meansof a pin, 10, adapted to a segmental slot, o, in the coverplate a; butthis is not necessary, and may be dispensed with.

I claim as my invention 1. The combination of the axle A, having acollar, to, the axle-box B, having a recess, b, and ribs d, the sleeveD, having a ring, 45, with ribs m, the cover-plate n, and the jam-nut F,

all substantially as specified.

2. The combination of the box B, having ribs d, with the sleeve D,having tapered ribs m, as described.

3. The combination of the recessed box B, having ribs 61, the axle A,having a collar, a, the packingrings 0c, and the sleeve D, having ribsm, with tapered faces, as set forth.

ln testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

GOTTLIEB FINKBEINER.
